UniProt Comments
Catalyzes the demethylation of isoprenylcysteine methylesters. In vitro, is specific for N-acetyl-S-farnesyl-L-cysteine methyl ester (AFCme) and has low activity toward N-acetyl-S-geranyl-L-cysteine methyl ester (AGCme). Acts as a positive regulator of ABA signaling. May be involved in the demethylation and inactivation of isoprenylated negative regulators of abscisic acid (ABA) signaling. Carboxyl methylation is a reversible and potentially regulated step in the post-translational modification of prenylated proteins.
